Fig. 7 is a cross-section of sleeve A theseseveral parts act will be separately deand shaft A of Fig. 7, takenbetween two scribed hereinafter. 50 of the wheels A Fig. 8 is across-section I will first describe the construction and taken throughthe ridding devices on line 8 8 operation of the adding mechanism A.

Referring to Figs. 1, 3, 5, and 8, X represents that part of the casingX that forms the housing for the adding mechanism, which housing isformed with a series of openings a through which shows the numberedfaces of a series of wheels A", Figs. 1, 3, 5, and 8. There is one ofthese wheels for the denomination of units, another for the tens,another for the hundreds, and so 011, each of which has numbers on itsperiphery from O to 9, equally spaced and arranged to show through theopenings to Each wheel A is formed with sprocket-teeth which connectwith a chain belt A, which passes over a corresponding largersprocket-wheel A A A &c., in the rear, which has twice as many teeth asthe series of wheels A Another series of sprocket-wheels A, Figs. 7 andS, is located below the chain belt and in engagement with it. Thisseries of wheels A has the same number of teeth as the wheels A andco-operates with the larger wheels for the purpose of carrying from onedenomination-wheel. to the next when the successive additions equal orexceed ten. This carrying is effected as follows: Motion is imparted tothe wheels A and A from the larger wheels A A A &c., in the rear. Thesehave each a lateral lyprojecting lug a, Fig. 8, for each notch or tooth.

A is an elbow-shaped detent pivoted on a shaft A and having anotch awhich drops down upon and holds successively each one of the lugs u",beingheld to this locked position by a spring a. On each of the wheels Ais a rigid radial arm and this arm of a wheel. A of one denominationacts upon the lugs a of the wheel A of next higher denomination-tliatisto say, supposing A, Fig. 7, .is a units-wheel, A the tens, and A thehundreds, the units-wheel A will act upon the first wheel A through itschain, and the small wheel A will, through its arm (t act upon the lugsa of the next wheel A Fig. 8, of the higher denomination at everycomplete rotation of wheel A, or whenever the aggregate sum of additionsequals or exceeds ten. As the wheel A rotates, its arm first lifts thedetent A until its notch a is oil? of lug a and the arm (t striking thatlug (1, turns wheel A of higher denomination one notch, the detent Aimmediately dropping back again and engaging the next lug a. As thewheels A A A" thus rotate they in turn transmit their motion through thechains A to the corresponding series of wheels A whose numbered facesshow through the openings (1. in the ease and indicate the totals of theaddition performed.

\Vhen the addition is completed and it is desired to eon'nnence on.other work, the wheels A must each be set back to the zeropoint. This isdone through the wheels A which are in gear with A through the chainbelts. Each wheel A has on its side a hollow boss, Figs. 7 and 7 with alaterally-projecting pin (1" in it. This pin on each wheel bears suchrelation that when carried to a certain point the zero-mark of wheels Awill show through the openings a These pins a" of the wheels A arerestored to this point as follows:

A, Figs. 7 and 7, is a hollow shaft on which the wheels A are hung. Thishollow shaft has a longitudinally-slidii1g stem. A within it, having aseries of radial pins a that protrude through a longitudinal slot in thehollow shaft A and lie normally within a recess (0 on one side of eachwheel A. A helical spring A lies within the end of the hollow shaft andforces the stem A outwardly, so that its pins a lie normallyin therecesses (1 aforesaid and afford no obstruction to the movement of thewheels. The end of the stem A terminates outside the ease in a handwheelor handle a and hasa radial key orbit a which, when the stem .is pushedin, passes through a keyhole a. \Vhen this stem is thus forced inagainst the tension of the spring A it causes all of the pins a to passout of their recesses a and to enter the hollow bosses of the nextwheels A, and then, when said stem is partially rotated, its pins on(see Fig. 7*) engage with the pins u of the whet s A in whateverposition they may be, and by turning them all to a predetermined pointrotate the wheels A through the belts and restore them all to zero. Todo this successfully it is necessary to unlock all of the detents A ofthe wheels A A A, (DUCK, and for this purpose the axial shaft A" hasoutside the case a rigid arm a, Figs. l and 8, which when deflectedcauses a lug or key 71' on said shaft to turn in the slot (7 in the detent A and simultaneously lift all of said detents. This slot a and luga" are necessary features of this part of the device, in order to permitan individual action of each detent A when lifted by a sliding bar A'and its cam a in carrying, whose operations will be describedhereinafter.

I will now describe how motion impartei'l to the wheels A A A from thegroupof k eys 13. These keys, Figs. 1, 2, and 3, are nine in number andare provided with faces numbered from 1. to 9, inclusive. They arearranged in sub-groups of three, the lirst group carrying the numbers 1L 3, the secoml :1. 5 t3, and the third 7 8 5). The front key of eachsub-group is made broad or elongated in horizontal direction and theother two of each sub-group lie immediately behind this broad. key. Thisis for the purpose of enabling the operator the more readily to locateand manipulate these keys without taking his eye off of the column offigures being added. As each group is constructed, arranged, andoperated alike, it will be snl'llcient to describe one with this furtherexplanation that each higher group has a little longer throw or movementthan the next lower one.

13, Figs. 1, 2, 3 and 5, is the main kcy-lever provided with a numberedface and carrying on the opposite sides of it two smaller key-levers B13 which are fulcrumed upon lateral pins 1) and forced by springs b,Fig. 1, to lie with their lower ends against stop-pins Z1 Figs. 3 and5,also projecting laterally from the main key-lever. The main key-leverB has a simple movement in transmitting its effect when depressed, butthe smaller or supplementary key-levers B have a compound movementthatis to say, when they-are depressed they first turn on their axial pins1), as indicated in dotted lines in Figs. 2 and 5, to bring their lowerends into engagement with co-opcrating devices, and then move down,carrying down the main key-lever B, which serves to support them, thusavoiding the necessity of multiplying the main key-levers. All of thesekey-levers, both the main levers B and the short ones B ,-act singly orindividually upon a depression-bar B fulcrumed on shaft R, Figs. 2, 2,5, and 9, with a different throw, but move it a uniform distance forfeeding or spacing, as hereinafter described. The different throw ofthese levers is determined by different stopping-points on the lowerpart, X of the case formed by slots in the case having bearings b 5 bFigs. 3 and 5, each one of which is alittle lower than the precedingone. \Vhen the main key-lever B is depressed it acts directly upon thedepression-bar B and also upon the middle bearing 1) of the case and isstopped by the latter, while the smaller key-levers 13 carried by it donot touch anything, because they are held out of range of suchengagement (see Figs. 2 and 5) by their springs I). lVhen, however, oneof them is depressed its lower end is first thrown into range ofengagement with the depression-bar and the slot-bearing b or U", asshown in dotted lines in Figs. 2 and 5, and its further de' scent withthe main key-lever causes it to come into contact with the bearing 5 orb of the case and the depression-bar. The stoppin g-points of thesethree levers of each group are so arranged that the short lever B on theleft of any group has the shortest stroke, the middle or main lever alittle longer stroke, and the short lever on the right still a longerone, and all these diiferent strokes are imparted through the one mainkey-lever of each group. It will be observed that the second groupcommences with a stroke a little longer than the long stroke of thepreceding group, so as to give a throw of a different range to each andevery one of the key-levers in order to cause each to turn theadditionwheels a different distance.

The main key-levers B are held up by springs 13*, Figs. 2 and 2, andimpart their throw to a rock-shaft under the housing. 'lo gear eachkey-lever B to the rock-shaft so it will be rocked by any one key-leverwithout affecting the others, the rock-shaft B has a key or feather I)that works in a curved slot U of each key-lever, (see Fig. 2%) and theseslots are constructed of different lengths and so graduated (as is wellknown in such devices) that the lever of shortest throw has the longestslot to permit of the maximum movement of the rock-shafts feather inthis slot without affecting that lever, and yet each lever by engagementwith the feather imparts to the rock-shaft the specific throw of each ofthe different keys.

The rock-shaft B is journaled in hangerbearings within the case and isprovided with a rigid sprocket-wheel B, Figs. 2 and 5, which through achain B Figs. 1, 2, and 5, imparts its motion to another sprocket-wheelB on a rock-shaft B above. This rock-shaft B has a rigid swinging arm 12carrying a spring-pawl b which engages with a ratchet wheel B on a loosegear-wheel B on rockshaft 13, and this gear-wheel engages a pin ion B onthe hollow shaft A (see Figs. 1 and 5,) and through the mechanism justdescribed transmits the throw of the key-levers B to the wheels A A A ofthe adding mechanism. To hold the ratchet-wheel B against backwardmovement while the working pawl b", Fig. 5, is taking a position foranew hold a back-thrust detent 1) Fig. 2, is provided beneath the upperfloor, F, of the case, the machine having a lower floor or base, Y, andalso an upper floor, F, which latter forms a support for most of theworking parts of the machine. Each or any of these wheels A A A &c., isindependently locked to the shaft A according to the denomination of therow of figures being added, by a device which connects with any one ofsaid wheels. This consists of a longitudinally-sliding-rod A (see Figs.1, 5, 7, and 8) which moves centrally within the hollow shaft A and hasa square bit a Figs. 7 and 8, that projects through the longitudinalslotin shaft A and is adapted to be thrown into the plane of theinternallyprojecting teeth a. of the wheels A A A to look any one ofthese wheels to shaft A without looking the others. The longitudinalmovement of the rod A is imparted by a vertical standard A, Fig. 4, towhich is also attached the parallel and horizontal slide-rods A and a.The former of these lies below the wheels A 'A A and has a cam a Figs. 4and 8, that lifts the detent A out of e11- gagemcnt of the samedenomination-wheel (A for instance) that is engaged by the bit a of theslide-rod A so that said wheel may turn. The slide-rod a lies above thewheels, being also attached to the standard A, and moves with the slide-rods A and A and carries an arm a, Figs. 3, 4c, 5, 7, and 8, that showsthrough a series of holes a in the outer case and always appears at thatopening directly over the wheel of that denomination which is beingadded, so that the operator may always know in what column of figures heis adding.

For shifting the standard A with sliderods A A a so as to bring the keysinto cooperation with any one of the wheels A A A a sliding rack-bar AFigs. 2 and 4, is connected to the standard A and is arranged inhorizontal position beneath the upperfloor of the casing, to be actedupon by a pinion A and a feeding mechanism hereinafter described.

I will now proceed to describe the printing devices shown at C. Theseconsist of a paperroll holder with means for feeding both vertically andhorizontally, a printing-ribbon, and an oscillating type-carrying andtype-operating device arranged to cause the type to press the ribbonagainst the roll of paper.

The paper-holder comprises an upper hollow roll, C, Figs. 1, 3, l, (3,and 9, provided with a coil-spring c, Fig. 9, within it after the mannerof a spring-roller for curtains. This hollow roll has a longitudinalslit 0' in its periphery, through which the end of the paper strip isinserted and in which it is retained by a longitudinal pinch-bar 0,having an eccentric Pl0jOCtiO11,W]llCil bar is journaled within bearingswithin the roll C and has a rigidly-attaehed rocking arm c, Figs. 5 andl), at the end outside the roll, which when rocked causes thepinch-barto act like a cam and tightly clamp the end of the paper stripagainst the inner edge of the slot. This rocking arm 0 also serves tolock the rollholder, so that its spring cannot exert any tension whileinserting the paper, and for this purpose the head of the arm in theopen position of the pinch-bar is made to enter a notch c in a rigiddisk on the framework, as shown in dotted lines in Fig. 5. Thespring-roller 0 holds the paper strip taut and smooth and also suppliesmeans for taking up the paper when fed in one direct-ion. The paperstrip P, which is wound upon this roll, passes (see Fig. 9) down infront of a rubber-faced platen and around a rubber-taced roll 0", andthence up and over a rubber-faced roll 0, which two rubber-faced rollssecure a frictional bite on the paper for feeding it down against thetension of the roll-holder or feeding it upwardly in response to thistension. The platen 0 constitutes the back-thrust bearing for the stripof paper, against which the force of the blow of the type (deliveredthrough the ribbon and paper) is borne. The two rubberli'aced rolls 0C", Figs. 5, t5, and 9, are geared together by two gear-wheels c 0, sothat they rotate together to feed the paper. All these rolls (1 C" C iand the platen are mounted upon a carrying-frame CF, which slideshorizontally upon two guide-rods O lixed in the main frame of themachine. One of these rods, C, passes through a tube a of theroll-frame, and the other, passes through the center of roll 0'. Theroll C has also a rigid sleeve extension C, Fig. (3, at one end whichcarries a hand-wheel C Figs. 6 and 9, and a notched disk 0 which latterby engagement with a spring-detent c, mounted on tube 0, delines theextent of movement for the roller C in its intermittent feed.

Rotary motion is imparted to the feed'rolls by a gear-wheel C, Fig. (3,fixed rigidly on the rear roll C and engaging with the long pinion oriluted roller 0 arranged beneath the same. This pinion C is made long,as a fluted roller, so that the gear-wheel C may receive motion from thesame always and at the same time be adjusted longitudinally inhorizontal direction from time to time as the paper is fed laterally, asis necessary in a horizontal progression of figures or changing from onedenomination to the next. To impart this horizontal longitudinal feed ofthe rolls a yoke O Figs. l, 5, (3, and i), embraces the earryinglrame Cand is formed on its lower side with a series of rack-teeth which engagewith a subjacent pinion (1/, and is held to contact therewith by anantifriction-roller a above. It will thus be seen that the lluted rollerforms the means for the transmission of the vertical or up-and-down feedto the paper,while the toothed yoke furnishes mea us for the lateral orhorizontal feed.

The pinion c has beside it and rigidly fixed on the same axis a bevelgear-wheel c", Fig. J, occupying a vertical plane, and the iluied roller0 has also at its end a rigidlyettached beveled wheel c Figs. 6 and S),occupying a vertical plane,but at right angles to the be velwheel c.Between these two bevel-wheels v 1; there is a double bevelwheel 0 whoseupper face is adapted to engage with the bevelwheel c when the doublebevel -whecl i s raised, as shown in Fig. 9, and whose lower face isadapted to engage with the bevelwheel 0, 2 shown in dotted lines, Fig.tgwhen the double bevel-wheel is lowered. This donble bevel-gearoccupies ahorizontal plane and is fixed upon a sleeve c which ismade adjust able on a vertical shaft 0 and forms the means for imparting thefeed motion either to the vertically-feeding devices through the upperbevel-wheel and tinted roller or to the lower bevel-wheel and toothedyoke. For imparting the vertical :uljustment to the double bevel-gearand its sleeve the latter is formed with corrugations c, which areengaged by a toothed segment c Fig. 9, formed on one arm of a rocleshaftc, Fig. U, and whose other arm c extends downwardly and is connected tothe upturned end of a slide-rod 0 moving in guides under the upper floorof the ease and connected, Figs. 1, 2, and 9, at the front end to thelower end of a thumbpieee F, which when tilted in one position throwsthe the slide-rod 0 back and when tilted to the other position throwsthe slide-rod forward, and thus by raising or lowering the doublebevel-gear c causes the feed of the paper to be vertical or horizontal,as may be desired. To define the throw of the slide-rod (1, Figs. 2 and9, a spring a is provided with alocking-pin e which is adapted to dropinto notches in the slide-rod at the end of its movement in eitherdirection and hold it iirmlyto place.

lVhile the shifting of the feed devices is effected through thethumb-piece F and sliderod C, the power for the actual feed is suppliedthrough another means. The sleeve 1;" of the double bevel-gear isconnected to its shaft 0 by a pin and grooves 0 Fig. 9, so that thesleeve turns with the shaft, although vertically adjustable on it, andthis shaft has at its lower end a bevel gear-wheel C Figs. 2, 6, and S,engaging with a bevel-pinion C on a horizontal counter-shaft C h un ginbearings under the upper floor of the case. The function of thecounter-shaft is primarily to effect the feed of the paper, and this itdoes either up or down or forward and backward, according to thedirection of movement of this counter-shaft. For this purpose thecounter-shaft has a large bevel-wheel C Figs. 1., 2, and 9, on its end,which is engaged alternately by one of two small bevel-pinions O O onopposite sides of the center of said large bevel-wheel, so as to imparta reverse motion to the same. The two bevel-pinions C C are fast on asleeve C having corrugations 0 with which engages a toothed segment-arm0 (see Figs. 2 and 9) on the lower end of a vertical rock-shaft 0 whoseupper end is provided with the reversing-lever E, (see Figs. 1, 2, 3,and 9,) and which when turned in one direction throws the bevel-pinion 0into engagement with the large bevelwheel 0 of the counter shaft andwhen thrown in the other direction throws the other bevel-pinion C intoengagement with said large bevel-wheel to rei erse the motion of thecounter-shaft. Motion is imparted to the sleeve CF from a central shaftC Figs. 2 and 9, which passes through other mechanism hereinafterdescribed and has a rigid pinion on its end engaging with a gear-wheel Cof a spring-motor G I will now return to the counter-shaft and explain afurther function which it has in addition to transmitting the power tofeed the paper. (See Figs. 2, 4, and 9.) On this counter-shaft C is thepinion A (see Figs. 2, 4, 6, and 9) which imparts the throw to therack-bar A standard A, and the sliderods A A and (L13 of the addingdevice, which effect the change from one denominationwheel to the next.This pinion A, Figs. 2 and 9, is loose on the counter-shaft, but isformed with a clutch section A that is adapted to be locked with theclutch A on a sliding sleeve A on the co unter-shaft,whieh sleeve has afeather-andgroove connection therewith. Said sleeve also has a set ofcorrugations (L20 with which engages the segmentheaded end of a lever AFig. 2, fulcrumed upon a pendent vertical pin and connected at its otherend with the slide-rod C, so that when the slide-rod is movedlongitudinally by its thumb-piece F to give the horizontal feed to thepaper in changing from one denomination column to the next the samemovement through the segment-headed lever A sliding sleeve A, and clutchcauses the pinion A on the counter-shaft to be locked to thecounter-shaft, and the latter then by rotating the pinion A moves therack-bar A longitudinally and adjusts the standard A" with itsslide-bars A a A horizontally to another denomination-wheel in theadding devices.

I will now proceed to describe how the keylevers B B act to print thenumbers on the paper of the printing devices.

T, Figs. 1, 8, 4, 5, and 6, are a series of type-levers. Nine of these011 one side of the center bear the printing-figures 1 to 9 and theothers on the other side have typefaces corresponding to the group ofkeys D. These type-levers are of a pot-hook shape and are fulcrumed attheir lower elbows to a flange f of a vibrating type-carrier Tconstructed as a plate occupying a vertical plane parallel to the paper.This type-carrier plate is pro vided with trunnions 2, Figs. 1, 4:, and5, that oscillate in bearings on the main frame. This type-carrier isnormally held in a vertical position, and when deflected to either sideof its normal position to bring any one of the type into strikingposition on the paper it deflects a spring-arm t, Fig. 4, of which thereare two, one on each side of the center of the type-carrier, and whichare connected to coil-springs '6 inside of housings 15 whose tensioncauses the arms to bear against lugs 15 on the carrier-plate and restoreit to the vertical position.

The carrier-plate T is oscillated to bring any one of its type intostriking position by a toothed segment T Figs. 5 and 6, fixed rigidly tothe plate and engaged by a corresponding toothed segment T fixed rigidlyon a rock-shaft T below the upper floor of the case. This rock-shaft,Figs. 2 and 5, has at its front end a rigidly-attached bevel-gear TFigs. 2 and 5, that may be engaged by either of two bevel gear-wheels Tor T one of which transmits the impulse of the keys B and the other theimpulse of the group of character-keys D. These bevel-wheels T T whichtransmit the impulse of the key-levers are fixed in the opposite ends ofa sleeve 25, which swivels in the lower forked end of the change-leverG, (see Figs. 2, 5, and 5%) and whose position serves to bring eitherthe group of number-keys B into co-operation with the type or thecharacter-keys D, according to whether bevel-wheel T is geared to T or Tis geared to T T coupling the number-keys B and '1 the character-keys D.

The sleeve t, Fig. 5, embraces the reduced end of rock-shaft B on whichthe numbered key-levers are hung and carries at this end the bevel-wheelT, and the sleeve at its other end carries bevel-wheel T" and embracesthe reduced end of a rock-shaft D, upon which the character-keys D arehung, the shafts D and B being in alignment and having their endsabutting within the sleeve i I have already described how the numberkeysB each impart a different throw to the rock-shaft B in turning theadding-wheels through the sprocket wheel and chain a different distancefor each key, and it will be easily understood that this different throwICC for the rock-shaft will impart for each of the number-keys throughbevel-wheels T and T (when engaged) a different throw to the typecarrierT, corresponding to the throw of the addition-wheels, so that eachnumber-key not only adds a corresponding number of digits on the addingdevices, but also turns the typeearrier so that its type, representingthat number, will be brought into position for depression. Thisdepression is offected by other devices which will be hereinafterdescribed in appropriate relation.

The character-keys l) (see Figs. 2, 3, and 9) work through slots [1 inthe outer casing, and these slots (with the exception of the last one onthe right, which is for the spacing-lever) are each of a differentlength, gradually increasing in length from left to right, so that thelovers of these keys will come to a stop, bearing against the bottoms ofthe slots, so as to cause each to give a different extent of movement tothe rock-shaft I) on which they are hung. This rock-shaft is turned bythe key-levers by a feather (7, Fig. 0, working in curved slots (1" ofthe key-levers, and these slots are of different graduated lengths tocause the feather of this rock-shaft to oscillate in the slots of allthe other key-levers after the manner of the feather on the rockshaft ofthe number-key levers. The keylevers D are raised by springs D one foreach lever. The throw of these levers imparts a different extent ofmovement to the rock-shaft D, and through its bevel-gear T (when engagedwith bevel-gear T imparts a throw to the typecarrier T of acorresponding length, so as to bring its corresponding type intoprinting position. This throw of the group of keys 1) on, thetype-carrier T is in the opposite direction to that of the numbered keysB by reason of the positions of the bevel-gears T T acting upon oppositesides of the bevel-gear T'", so that the type-carrier is moving in onedirection over to one side of its middle line by the number-keys, and inthe other direction and over to the other side of its middle line by thecharacter-keys.

I will now describe the function and operation of the depression-bar13". (See Figs. 2, 5, and 9.) This runs along the front of the machineand is acted upon by all of the keys except the spacing-key, which isthe last key on the right of Fig. 1. This depression-bar is in thenature of a yoke rigidly attached to a rock-shaft R and forced u1)wardly by a spring R, Fig. 2*. This rock-shaft it through the action ofthe keys upon the depressionbar is made to perform several functions, asfollows: It locks the addition-wheels against being thrown too far bymomentum it also feeds the type writer ribbon, and it also further locksthe type-carrier against being thrown too far by momentum, all of whichis effected through arigid upwardly-projeeling arm R and pitman R, Figs.2 and To look the addition devices a short rock shaft 0" is journaled inbearings beneath the upper floor of the ease and has one arm 1"connected to the pitman it", (see Figs. and 5,) and another arm 0',which is constructed as a detent that engages with the teeth of aratchet-wheel R", fixed fast on the gear-wheel B of the adding devices.This detent cngages the ratchet-wheel it and locks the addiug-wheels atthe end of the throw of the adding-keys.

To move the type-writer ribbon it, 1, 2, 4, 5 and 6, a spring-pawl 9",carried by the pitman R, Fig. 5, engages a ratchet-wheel R on ahorizontal shaft R, Figs. 2 and t, journaled in hangers under the upperfloor of the case. This shaft has a bevel-wheel It at one end and abevel-wheel R at the other, and these engage, respectively, with otherbevel-wheels R" R on the lower ends of vertical shafts R R, (see Figs.1, 2, i and 6,) which at their upper ends carry spools or reels R R thatcarry the type-writer ribbon it, Figs. 1., i and J, one spool paying offthe rib bou and the other spool taking it up at each intermittentmovement of the subjacent shaft It, as effected by the spring-pawl. rand ratchet vheel R, through the pitnian l t and the depression-bar B.

To look the type-carrying frame against momentum at the end of the throwsaid frame is extended below the lloorof the ease, Figs. 2, -l-, 5, and6, and is provided with a curved row of teeth R with which there engagesa detent or locking arm on a rock-shaft r, which has at the opposite enda crank-arm 1' that is connected to the pitman it, and whose actionmoves the detent-arm 0* into engagement with the teeth on the lower endof the type-carrier frame whenever it has reached the limit of its throw. To prevent the lateral bending of the detent-arm 1' its end iscarried in a detent-guide or slotted bar '1', Figs. 5 and (J, fixed to arigid part of the framework.

I will nowproceed to describe how the typelevers when brought intoproper position to print are forced against the ribbon and are made todeliver an impression on the paper. This is effected through the powerof the spring-motor (T before referred to.

M, Figs. 5 and 6, is a vertical impact-bar arranged in a centralposition just behind the type-lever carrier and arranged to rise with asudden upward movement and deliver a blow upon the lower end of any oneof the type-levers which causes the latter to move rearward at theirupper ends, and deliver a blow against the ribbon and paper and thenfall back from gravity to a resting place against the upper edge of thetype-carrier again. This impact-bar slides vertically in a trunnionedguide m and has a screw-sleeve m in its length which permits it to beadjusted vertically. At its lower end it is jointed to a crank-arm m ona horizontal rock-shaft M, journaled in bearings under the upper floorof the case. (See Figs. 2 and 5.) This rock-shaft has anotherdownwardly-projecting crank-arm M Figs. 2 and G, which is connected witha pitman M through which power is transmitted from the spring-motor 0 asfollows, (see Figs. 2 and 2%) The pitman M Fig. 2, terminates at itsfront end in an eocentric-strap which embraces an eccentric-hub M Figs2" and 2 fast upon a disk M Beside this disk is another hollow disk Mwhose chamber faces that of the other disk. WVithin the hollow disk is acoiled spring M one of whose ends is attached to one disk, M and theother end to the other disk, M. Both these disks are loose on the shaft22 through which the paper is fed. On this same shaft and rigidlyattached to it beside the hollow disk M is another disk M which is fastto and derives motion from the pinion C which is also fast upon theshaft 0 and which is in gear with the transmitting gear-wheel 0 Fig. 2,of the motor. Before describing this mechanism in detail I would statethat its eifect is to take the power of the motor and intermittentlystore it up in the coil-spring M of the hollow disk and then through anescapement m m m m m set into operation by the keys to let out thetension of this coil-spring M in a single rotation of the disk M whichthrough its eccentrio-hub and the pitman M causes the impact-bar todeliver a blow upon the typelevers. For this purpose the disk M haslying against the hollow disk M a collar m with a shoulder m, Fig. 2, onit, which, as the disk M rotates from the power of the mo tor, catchesagainst a spring-pawl m on hollow disk h and turning this disk puts thecoil-spring within it under tension, which tension is imparted throughthe other end of the coil-spring to the other disk M This latter disk isheld against the tension of the coil-spring within the disk M by theescapement, which is set into action by the depression-bar B through theaction of the keys. For this purpose the depressionbar has a rigid armM", Figs. 2, 2, 2 and 2 that has near its inner end two lugs m m Fig. 2,that are arranged to be struck by two pins m 012, on the disk M to limitthe rotation of the latter-that is to say, when the arm M of thedepression-bar is in one position the lug m stands in the path of thepin m and when the arm M is moved to its other position (indicated bydotted lines) the lug m is taken out of the path of said pin, and thedisk is allowed to rotate once from the tension of coilspring M but thesame movement of the arm brings its other lug on into the path of thepin m so that the latter strikes it at the end of the rotation, and thusa step-by-step escapement is provided in which the tension of thecoil-sprin g M is expended in producing a single rotation of the disk Mand imparting a printing movement to the pitman M and impact-bar M.

Beside the arm M of the depression-bar is another arm M Figs. 2 and 2,which has two stop-lugs on m, which act upon pins m m of the disk M and,acting as an escapement thereupon in the same manner, causes anintermittent discharge of the power of the motor through the same towind up the coilspring l in the hollow disk at each depression of akey-lever and movement of the depression-bar B Thus the power of themotor, as thus broken up into intermittent impulses, is directed throughthe disks on the shaft 0 to the printing devices.

I will now describe how the spacing is effected without setting intooperation the printing devices.

The last one of the group of character-keys on the extreme right is thespacing-key. This key has a long lever D Figs. 2, 2 and 2 terminating atits inner end in a right-angulartooth d and held by an independentspring D", so as to hold said tooth back and hold the key up. This toothof this lever is in the plane of the hollow disk M, whose periphery isprovided with a notch 01 directly opposite the elbow of its spring-pawlm The lever D of this space-key is also provided with a pin cl, thatplays in a slot in a curved bar D, which is attached to thedepression-bar arm M said arm M being connected to arm M by apivot (Zand a spring 61 Figs. 2 and 2 Now when the space-lever is depressed itstooth d at its lower end enters the notch of disk M looking it asagainst any backlash, and at the same time strikes against and deflectsthe spring-pawl m nulocking this disk from the rigid disk M This cutsout the transmission of power to the pitman and printing devices. Thenas the lever D moves farther its pin 61 reaches the end of the slot incurved bar D (see dotted lines, Fig. 2 deflects it, and also thespring-hinged arm M of the depression-bar, and allows the stop-lugs m mon this arm to work with the rigid disk M for transmitting a rotation ofthe same from the motor to the shaft 0 and the adding and paper-feedingmechanism without working the printing devices.

In some cases in preparing a balance-sheet or statement of account itwill be necessary to space continuously without either adding orprinting. done.

N is a thumb-lever, Figs. 2 and 2", projecting throughthe front of thecase and having its end which projects into the case arranged to bearupon the curved bar I), Fig. 2", of the pivoted arm M which controls themotor escapement disk M Fig. 2 through its lugs m m". \Vhen thespacingkey lever D is pressed and its locking-tooth on the inner endengages and holds the hollow disk H to lock the printing mechanism, thethumb-lever N is at the same time lifted, and this action throws downthe curved bar 1) and pulls the arm M", with its two lugs m m entirelyaway from the pin of rigid disk M as in dotted lines, liigs. 2 and 2".The motor is now free to continuously expend its power on this disk Mand its .rigid shaft, which continuously moves the paperfcedingmechanisn'i without either adding or printing. To keep the motor and thepaper- :t'eeding mechanism from speeding when thus allowed to operatecontinuously, I provide a brake-lever N, which by the simultaneousaction of the thumb-lever N is thrown against a brake-wheel N Figs. 2and 1, provided for the motor, which retards the motor movement andmakes it fast or slow, according to the amount of pressure exertedthrough the thumb-piece and brake-lever.

In some cases it may be necessary to operate the printing and feedingmechanism without operatii'ig the adding devices, and for this purpose Iprovide (see Fig. on the oscillating pawl-arm l), which turns the mainworking-ratchet of the adding-wheels, a thumbpiece I, which has a cam ton the lower end of the same, which, when the thumb-piece turned oneway, throws the spring-pawl I) out of the ratchet l3 and allows the armto oscillate without actuating the adding-gear. \Vhen this thumb-pieceis turned into another position its cam allows the pawl to drop toengagement with the ratchet-teeth again and the adding-wheels are againthrown into operative connection with the keys.

\Vhen the type-levers are advanced to striking contact with the ribbonand paper, the ribbon lies ilat against the paper and close to it, butwhen the type-levers fall back again the ribbon is withdrawn laterallyfrom the paper so that the operator can see the impression made, andwhereby also the feed of the ribbon is prevented from smearing orblurring the paper. This is effected (see Figs. ll, 47, f), and bycarrying the ribbon through pairs of radial pins 0 0 o 0 on a rock-shaftO extendinghorizontally in front of the platen and parallel with thesame. This rock-shaft is journaled at its ends in upright posts 0 O,which have ribbonguides on their upper ends, and said rock-shaft isworked by a rigid arm 0 Fig. 9, a vertical connecting-rod o, and acrank-arm 0 on the oscillating shaft M of the impact-ha r, so that afterevery printing-impact the rod 0 is pulled down and the I will nowdescribe how this is ribbon rock-shaft O is turned so as to throw theradial ribbon-pins 0 o o o away from the platen, as in Fig. 5, thusremoving the ribbon from the paper by a lateral movement that leaves theimpression in full view, and also avoids smearing the paper when theribbon is fed along.

\Yhen it is necessary to reverse the feed of the ribbon, this isaccomplished (see Fig. l) by a llat reversing-key 0* which enters a slot0 in either of the spools 1W and also a slot in the upper end of thespool-shafts R R. \Vhen this key is inserted in these two registeringslots it looks that spool to that shall, and when the feed of the ribbonis to be reversed this key is taken out of one spool, 11, (in which itnow appears,) leaving that loose on its shaft, and is inserted in theother spool,

t locking that rigidly on its shaft, and thus reversing the food.

When the adding mechanism is thrown out of gear by its clutch A A, (seeFig. 2,) it is desirable to lock and hold the raelvbai-A againstaccidental movement, and for this purpose a spring-detent a, isprovidcd,whose tooth lies upon the periphery of the clutchsection A", and whenthe clutch-section has its recesses closed by the lugs of the otherclutch-section A said detent merely slides on the periphery and has noeliect, but when the lugs oil the clutch-section A leave the recesses ofthe other clutch-section, as shown, said spring-detent drops into suchrecesses and locks the adding mechanism. ll'hen the clutch is re-engagedthe tapered lugs ol the clutch-section A, Fig. 9, slide under the toothof the spring-detent a and force it out of the recesses inclutch-section A".
